ABSTRACT:
In methods of and apparatus (28) for indexing a repetitively patterned strip (12) past a plurality of work stations, such as, for example, a bonding station (33) and a dewebbing station (65) of a lead frame bonder, a cyclical, automated adjustment of the strip (12) with respect to the bonding station (33) eliminates repeated meticulous manual fine adjustments of the strip. An adjustment of the position of the strip (12) is achieved by adjusting the positions of travel limit stops (109 and 111) of an incremental feed mechanism (46). Simultaneously with the adjustment of the travel limit stops (109 and 111), an adjustment is made in the same magnitude and in the same direction as the adjustment to the limit stops in the position of the dewebbing station (65). Similar adjustments may be made to any other station, an accurate position of which with respect to the position of the strip (12) is desirable.
